Credit Loans
Understanding borrowing, interest calculations, monthly repayments, and the true cost of credit
Credit and loans are important topics because borrowed money always comes with conditions. Learners must be able to read those conditions and work out what the loan will really cost.
Understanding Credit Loans
A credit loan is a sum of money that is borrowed from a lender, which is expected to be paid back with interest over a specified period. Credit loans can take various forms, including personal loans, car loans, and home loans. Understanding the terms and conditions associated with these loans is crucial for making informed financial decisions.

Key Mathematical Concepts Related to Credit Loans
Simple Interest
Simple Interest = P × r × t
Calculated only on the principal amount of the loan.
Compound Interest
A = P(1 + r/n)^(nt)
Calculated on the principal and also on the accumulated interest from previous periods.
Monthly Repayment Formula
M = P × [r(1 + r)^n] / [(1 + r)^n - 1]
Calculates the fixed monthly payment required to repay a loan over a specified period.
Total Cost of the Loan
Total Cost = M × n
The total amount repaid over the life of the loan, including both principal and interest.

Practical Applications
Personal Loan for a Laptop
A student needs R8,000 for a laptop. They take a personal loan with 10% simple interest per year over 2 years.
Interest = R8,000 × 0.10 × 2 = R1,600
Total = R8,000 + R1,600 = R9,600
Monthly = R9,600 ÷ 24 = R400 per month
Car Loan Comparison
Car for R120,000. Bank A: 11% over 5 years. Bank B: 9.5% over 4 years.
Bank A: Total R186,000, Monthly R3,100
Bank B: Total R165,600, Monthly R3,450
Bank B saves R20,400 interest but costs R350 more monthly
Home Loan Affordability
House for R800,000 with R100,000 deposit. 8.5% compound interest over 20 years.
Loan amount = R700,000
Monthly payment ≈ R6,078.65
Total cost = R1,458,876, Interest = R758,876
